Controller for power converter

Abstract

A controller for a power converter that includes a multilayer board; a microcomputer that is implemented in a first area on one surface of the multilayer board; a power IC that is implemented in a second area on the other surface of the multilayer board; and a wiring that is formed in the multilayer board, and connects the microcomputer and the power IC to each other, wherein the second area is configured to be included in the first area when viewed in a normal direction of the multilayer board, and the multilayer board includes a portion of a ground potential in the second area when viewed in the normal direction of the multilayer board.
